Description:
When importing from CSV, the "Format quoted fields as text" provides a way to distinguish text from numeric fields.

However the corresponding export-to-CSV feature is missing: There is no way to generate a CSV with Text fields quoted.  So the format gets lost in a round-trip from spreadsheet to CSV and back to spreadsheet (often needed to use text-oriented tools to manipulate the data).

IMO exporting to CSV should, by default quote fields which have Text (not numeric) format even if they don't contain special characters (for example numers).

Steps to Reproduce:
1. Load attached demo.ods spreadsheet; verify that the format of A2 is Text and B2 is Number(General)
2. File->Save As... change file Name and set output drop-down to Text CSV(.csv)
3. File->Open...  navigate to the saved .csv file
     Check "Format quoted field as text"
4. Check format of A1 (rightclick->Format Cells...->Numbers:Category)

Actual Results:
A2 has numeric format in the imported document, rather than Text

Expected Results:
Export should have quoted A2 because it was Text, so it could be imported as Text
